Abstract
Objective
The objective was to evaluate the efficacy of diffusion-weighted imaging (DWI) in
predicting the development of vascularization in hypovascular hepatocellular lesions
(HHLs).
Materials and methods
Forty-two HHLs that were diagnosed by computed tomographic (CT) arteriography were
evaluated retrospectively. The lesion on DWI was classified as isointense, hypointense,
or hyperintense. Follow-up studies that included intravenous dynamic CT or magnetic
resonance imaging were performed.
Results
The 730-day cumulative developments of vascularization in hypointense, isointense,
and hyperintense lesions were 17%, 30%, and 40%, respectively. The differences among
these developments were not statistically significant.
Conclusion
The signal intensity on DWI showed no significant difference in the development of
vascularization.
